Tower may be a "reputable "firm to you I have quite a different experience with them and so do others. I dealt with them as far back as 1977(when they were honest businessmen)not so today. case in point- upon purchasing a scratch n dent engine I was subject to intense sales pressure to purchase props (on sale) for the engine that were completely unsuitable. also intense pressure to join their buying club which would have been of little benefit to me.real arm twisting. there are others.I have dealt with 4 other major mail orders and only one other has my experience been bad. none of the others sent me weekly sales bulitins urging me to buy or I'd get dropped.Tower is essentially a buying machine,both for whole sale & buying out the older hobby lines &eliminating them. Tower also spread false rumors at one time about SIG MFG being in finacial straits.many hobby shop dealers recieved the letter. i saw it myself. mostly because Hazel would not sell out to them..
